Embodiment
In the typical urban/suburban environment of the U.S., can see the covering of at least three kinds of dissimilar Access Networks, such as mobile communication (" GSM "), code division multiple access (" CDMA ") and WLAN (wireless local area network) (" WLAN ") focus.These focuses may be privately owned.For in these type Access Networks each, find a plurality of service providers possibly such as the equipment of mobile radio station.The utilization of each is all different in these Access Networks.For example, when the GSM network over loading, the WLAN focus may have enough available bandwidths.Equally because deployment constraints and not enough capacity, so when CDMA operator may be when same position has active volume, GSM carrier's network may transship.Under these circumstances, current forward device provides the Access Network of service may find that it is useful that user/equipment is moved to another Access Network.This will satisfy both sides service provider's needs.That is to say that second Access Network can be bought user's traffic/session from first Access Network, to alleviate the congested of first Access Network or to reduce the cost of first Access Network.
From conceptive, this is similar between network and roams.Yet roaming needs prearranged agreement.The emphasis of instruction described below is the negotiation that enables right, with between a plurality of different Access Networks with in real time, be specific mobile radio station service in the mode of ad-hoc.These instructions also relate to wired line phones company and sell the Wireline bandwidth with the form of phonecard.These instructions are at being auctioned by user's (or software on the subscriber equipment) bid rather than bandwidth.Simultaneously, the user is under the control of holding the current Access Network of parameters for authentication for example.
These instructions provide the transaction of enabling business prototype element, and in this business prototype, the Access Network with active volume can " be bought the user " from incumbent Access Network.This will make littler network (even having the privately owned WLAN access point owner) can obtain income from their excess bandwidth.The resource of being sold is that user's (having some restrictions) and buyer are competition networks.Therefore, this system provides practicable business prototype.
Transaction between Access Network has utilized token.Token comprises a plurality of information (comprising device identification) about equipment, about main service provider's information, information, quality of service requirement and interim effectively user's authentication information about current Access Network.
Token can be stored in the network neutralizing device.Alternatively, token can only be stored in the network.Token can be available always, and perhaps token can only generate when the user is sold in the current network decision.
The token that is stored in mobile radio station is different from the token that is stored in the Access Network slightly.That is, the token that is stored in mobile radio station has the authenticate key that the authenticate key with the token of Access Network complements one another.Second Access Network will need above two token authenticated user and corresponding service will be provided.
User's sale refers to the real-time financial agreement between first Access Network and second Access Network, and wherein, in the duration of consulting, user's business is carried via second Access Network.In return, second Access Network obtains money or some other interests.Alternatively, Access Network can rather than be consulted in the duration in the calling of some or session.According to various embodiment described below, various Access Networks can all insert share service device or core net, or insert each other server or core net.That is, after second network obtained the user, under the situation of the resource of not using first service provider, second service provider provided the method that routes the call to the user by second network for first service provider.The internet provides to be set up and the simple method that is connected a plurality of networks.
As discussed below, Fig. 1 and Fig. 2 have described the network that is used to have available bandwidth is bought the business of mobile radio station or mobile radio station from user's main service provider agreement.This process has guaranteed that the decision that when and whether can move to alternate network about mobile radio station controlled by main service provider.The business that sends mobile radio station by mobile radio station on all air interfaces of the position that is deployed in mobile radio station can trigger this process for the indication of buying.
